Website Planning Checklist: What to Decide Before Development Begins

Introduction

Planning a website before development begins can save your business significant time, money, and unnecessary revisions. A well-planned website gives designers and developers a clear direction, reduces confusion, and creates a stronger foundation for SEO, user experience, performance, and future growth.

Before writing code or starting design, there are several decisions your business should make. From defining website goals and target audiences to deciding on pages, features, technology, content, integrations, and SEO requirements, each decision influences the final website.

This website planning checklist walks you through the most important things to decide before development begins.

If you are starting from the beginning, it is also useful to review our guide on How to Plan a Business Website Before Development, which covers the broader planning process.

Why Website Planning Matters Before Development

A website project can quickly become complicated when important decisions are left until development has already started.

For example, changing the website structure after development can affect URLs, navigation, content, database structures, and SEO. Adding major functionality later may require additional development work. Even seemingly small changes can create delays when they affect multiple parts of the website.

Planning helps establish:

• Clear business objectives

• Defined target audiences

• A logical website structure

• Required pages and content

• Functional and technical requirements

• Design direction

• SEO requirements

• Third-party integrations

• Security and performance expectations

• Launch and maintenance requirements

The goal is not to predict every detail perfectly. Instead, the purpose of planning is to create a clear framework that developers, designers, content teams, and business stakeholders can work from.

Website Planning Checklist: What to Decide First

Use the following checklist before development begins.

1. Define the Main Purpose of the Website

Start by answering one fundamental question:

What should this website accomplish for the business?

A website might be designed to:

• Generate leads

• Sell products online

• Promote professional services

• Build brand awareness

• Provide information

• Generate enquiries

• Support existing customers

• Publish educational content

• Showcase a portfolio

• Build an online community

A business website can have several objectives, but it should have clear priorities.

For example, a service-based company may primarily want qualified enquiries, while an ecommerce business may focus on product discovery and completed purchases.

Clearly defined objectives make it easier to determine which pages, features, calls to action, and conversion paths the website needs.

If you have not defined these yet, start with website goals and objectives before moving into design or development.

2. Identify Your Target Audience

Your website should be planned around the people who will actually use it.

Define:

• Who your primary customers are

• What problems they are trying to solve

• What information they need

• What questions they commonly ask

• What motivates them to take action

• What objections may prevent conversion

• How familiar they are with your products or services

You may have multiple audience groups, but identifying the primary audience helps prevent the website from becoming too generic.

Audience research also influences website messaging, navigation, content structure, calls to action, and user experience.

3. Establish Your Website Goals and KPIs

Business goals explain what you want the website to achieve. KPIs help you measure whether it is achieving those goals.

Depending on the website, useful KPIs might include:

• Contact form submissions

• Qualified leads

• Online purchases

• Booking requests

• Phone calls

• Newsletter sign-ups

• Product enquiries

• Downloads

• Organic search traffic

• Conversion rate

• Engagement with important pages

Decide which metrics matter before development so that the necessary tracking can be incorporated into the website from the beginning.

4. Decide Which Pages the Website Needs

Before development starts, create a preliminary list of website pages.

A typical business website may include:

• Home

• About

• Services

• Individual service pages

• Products

• Product detail pages

• Portfolio or case studies

• Blog

• Contact

• FAQ

• Privacy Policy

• Terms and conditions

The exact structure depends on the business.

Avoid adding pages simply because other websites have them. Every page should serve a purpose for users, search engines, or business objectives.

For a more detailed approach, review Website Page Planning: Which Pages Does Your Business Website Need?

5. Create the Website Structure

Once you know which pages you need, determine how they should relate to one another.

For example:

Home → Services → Website Development → Contact

or:

Home → Products → Category → Product → Checkout

The structure should make it easy for visitors to understand where they are and where they can go next.

A well-organised website structure can also support SEO by creating clear relationships between related pages.

This is where your website structure, navigation, and sitemap planning should work together.

6. Plan the Website Sitemap

A sitemap provides a structured overview of the website's pages and hierarchy.

Before development, determine:

• Main navigation pages

• Subpages

• Service or product categories

• Blog categories

• Important landing pages

• Supporting content

• Potential future pages

The sitemap can also help identify missing pages, unnecessary duplication, and opportunities for better internal linking.

A clear sitemap gives developers and content teams a shared understanding of the website before implementation begins.

7. Decide on the Navigation

Website navigation should reflect the way users are likely to explore your content.

Decide:

• What belongs in the primary navigation

• Which pages should be grouped together

• Whether dropdown menus are required

• Whether a search function is necessary

• What should appear in the footer

• Where important calls to action should appear

Keep navigation focused on the most important user journeys rather than trying to expose every page from the main menu.

8. Decide What Content Is Required

Development and content planning should not happen independently.

Before development, identify:

• Required page copy

• Headlines

• Calls to action

• Product descriptions

• Service descriptions

• Images

• Videos

• Case studies

• Testimonials

• FAQs

• Blog content

• Downloadable resources

Also decide who is responsible for creating, reviewing, and approving the content.

Content should ideally be considered before design because the amount and type of content can influence layouts and components.

For a deeper approach, see How to Plan Website Content Before Development.

9. Prepare Your Website Requirements

Your developer needs more than a list of pages.

Document functional and technical requirements such as:

• Contact forms

• User accounts

• Search

• Filters

• Booking functionality

• Ecommerce

• Payment processing

• Customer dashboards

• Calculators

• File uploads

• Notifications

• Admin functionality

• Content management

• Third-party integrations

Clearly documented requirements reduce assumptions during development.

10. Decide Which Features Are Essential

Not every possible feature needs to be included in version one.

Separate features into:

Must-have features

Functions required for the website to achieve its primary objectives.

Nice-to-have features

Useful improvements that can potentially be added later.

Future features

Ideas that may become relevant as the business grows.

This approach helps prevent scope creep and keeps the initial project focused.

A website features checklist can help you evaluate which functionality your business actually needs.

11. Choose the Right Technology

Technology decisions should be based on business requirements rather than trends alone.

Consider:

• Website type

• Expected traffic

• Content requirements

• Ecommerce needs

• Custom functionality

• Integrations

• Scalability

• Security

• Maintenance requirements

• Budget

• Internal technical capabilities

Depending on the project, you may use a CMS, ecommerce platform, custom development framework, or another technology stack.

The important thing is choosing technology that supports the website's current requirements while allowing reasonable future growth.

12. Decide on the CMS and Content Management Process

If your team will regularly update the website, decide how content will be managed.

Consider whether your team needs to:

• Create blog posts

• Edit page content

• Add products

• Upload images

• Manage categories

• Update FAQs

• Publish landing pages

• Manage users

• Review submissions

The CMS should match the team's technical capabilities and the complexity of the website.

13. Establish the Design Direction

Before visual design begins, define the general direction of the website.

Consider:

• Brand colours

• Typography

• Logo usage

• Visual style

• Image style

• Button styles

• Layout preferences

• Brand personality

• Existing brand guidelines

You do not need to design every page yourself. However, providing a clear design direction can make the design process more efficient.

A website wireframe can also help establish layout and functionality before detailed visual design begins.

14. Plan the User Experience

Think about what users should do after arriving on each important page.

For every major page, ask:

What does the visitor need to know?

What action should they take next?

What could stop them from taking that action?

For example, a service page might guide visitors from:

Problem → Solution → Benefits → Process → Proof → FAQ → Call to Action

Planning these journeys before development helps create a website that supports both usability and conversions.

15. Plan Your Calls to Action

Every important page should have a logical next step.

Depending on your business, calls to action might include:

• Contact us

• Request a quote

• Book a consultation

• Buy now

• Get started

• Download the guide

• View the service

• Call the business

• Submit an enquiry

Avoid giving every page the same generic CTA if users have different intentions.

The call to action should match the purpose and stage of the user's journey.

16. Plan SEO Before Development

SEO should not be treated as something added after the website is finished.

Before development, consider:

• Primary keywords

• Search intent

• URL structure

• Page hierarchy

• Metadata

• Heading structure

• Internal linking

• Image optimisation

• Mobile performance

• Page speed

• Schema requirements

• XML sitemap

• Robots.txt

• Canonical URLs

• Redirect requirements

Technical SEO decisions can affect the architecture of the website, so they are easier to implement when considered early.

17. Decide on URL Structure

URL planning is particularly important for SEO and future website maintenance.

Decide how URLs will be structured for:

• Services

• Products

• Categories

• Blog posts

• Locations

• Landing pages

Aim for URLs that are logical, readable, consistent, and unlikely to change unnecessarily.

If the project is a redesign, identify existing URLs that need to be preserved or redirected.

18. Plan Third-Party Integrations

Make a list of every external system the website needs to connect with.

Examples include:

• CRM systems

• Email marketing platforms

• Payment gateways

• Analytics platforms

• Booking systems

• Social platforms

• Marketing automation tools

• Customer support systems

• Inventory systems

• Shipping providers

Identify the required integrations early because they can affect both development effort and project timelines.

19. Decide on Analytics and Tracking

Determine what needs to be measured from launch.

Depending on your objectives, this could include:

• Traffic sources

• Form submissions

• Button clicks

• Purchases

• Downloads

• Calls

• Search performance

• Conversion paths

Make sure tracking requirements are communicated before development is completed rather than trying to reconstruct them later.

20. Plan Mobile Responsiveness

Your website should be planned for different screen sizes from the beginning.

Consider how important elements will work on:

• Mobile phones

• Tablets

• Laptops

• Desktop monitors

Pay particular attention to navigation, forms, buttons, images, tables, product listings, and interactive components.

Mobile responsiveness should be part of the design and development process, not an afterthought.

21. Establish Performance Expectations

Website performance can affect both user experience and search visibility.

Before development, decide that the website should prioritise:

• Fast page loading

• Optimised images

• Efficient code

• Appropriate hosting

• Mobile performance

• Limited unnecessary scripts

• Efficient third-party integrations

• Core Web Vitals

Performance requirements should be considered alongside design and functionality because visually complex features can sometimes affect loading speed.

22. Plan Website Security

Security requirements depend on the type of website.

At minimum, consider:

• HTTPS

• Secure authentication

• Strong password practices

• Form protection

• Software updates

• Secure integrations

• Backup procedures

• Access control

• Protection against spam and malicious submissions

If the website handles sensitive customer or payment information, additional security requirements may be necessary.

23. Decide on Hosting and Domain Requirements

Before launch, establish who manages:

• Domain registration

• DNS

• Hosting

• SSL

• Business email

• Backups

• Server access

Make sure ownership and access credentials are properly documented and controlled by the business.

24. Define the Project Scope

One of the most important decisions is determining what is included in the initial project.

Document:

• Number of pages

• Features

• Integrations

• Design requirements

• Content responsibilities

• SEO scope

• Testing requirements

• Migration requirements

• Launch support

A clear scope makes it easier to manage expectations and avoid uncontrolled additions during development.

25. Set the Budget and Timeline

Your budget and timeline should reflect the actual requirements of the website.

Factors that can affect cost and duration include:

• Number of pages

• Custom design

• Custom functionality

• Ecommerce

• Integrations

• Content creation

• Migration

• SEO requirements

• Testing

• Third-party services

A realistic website development timeline should account for planning, design, content, development, testing, revisions, and launch—not just coding.

26. Assign Responsibilities

Website projects often involve several people.

Decide who is responsible for:

• Project management

• Content

• Design approvals

• Development decisions

• SEO

• Technical access

• Legal approvals

• Testing

• Final approval

Having clear ownership prevents projects from getting delayed because nobody knows who needs to make a particular decision.

27. Prepare a Website Launch Checklist

Before development begins, think ahead to launch.

Your eventual launch checklist should cover:

• Content review

• Forms

• Links

• Mobile responsiveness

• Browser compatibility

• SEO metadata

• Redirects

• Analytics

• Security

• Performance

• Sitemap

• Robots.txt

• Backup

• Domain and DNS

• Final stakeholder approval

Planning these requirements early makes the final launch much smoother.

Common Website Planning Mistakes to Avoid

Starting Development Without Clear Requirements

When development starts before requirements are documented, important functionality can be missed and assumptions can quickly lead to revisions.

Treating Content as an Afterthought

Designing layouts without knowing what content they need to contain can create problems later. Content, structure, and design should be planned together.

Adding Features Without Prioritisation

A long feature list does not necessarily produce a better website. Focus on features that directly support business and user objectives.

Ignoring SEO Until Launch

Changing URLs, page structures, navigation, or content architecture after development can create unnecessary SEO complications.

Not Planning for Future Growth

Your website does not need every future feature on day one, but its architecture should avoid making reasonable future improvements unnecessarily difficult.

Underestimating Stakeholder Decisions

Projects can stall when approvals are unclear. Establish who makes decisions and how feedback will be collected before development begins.

How This Checklist Fits Into the Website Planning Process

Website planning works best as a sequence rather than a collection of isolated tasks.

A practical process looks like this:

Business Goals → Target Audience → Website Structure → Pages → Content → Features → Technology → UX → Design → SEO → Development → Testing → Launch

Each stage informs the next.

For example, defining the target audience influences website content and user journeys. Those user journeys influence page structure and navigation. The required functionality then influences technology and development requirements.

This is why planning before development can have such a significant impact on the final result.

Final Thoughts

A successful website project starts long before the first line of code is written.

By deciding your goals, audience, pages, structure, content, features, technology, SEO requirements, integrations, budget, timeline, and responsibilities in advance, you give your development team a much clearer foundation to work from.

The purpose of a website planning checklist is not to make every decision permanent. Some details will naturally change during design and development. The goal is to identify the important decisions early enough that changes do not become unnecessarily expensive or disruptive.

The more clearly your business can define what the website needs to achieve and how it should work, the easier it becomes to build a website that is useful for visitors, manageable for your team, and capable of supporting long-term growth.
